This paper provides a small-scale exploration of the evolvement of leadership roles in higher education academic units (AUs), namely Departments, Schools & Faculties. A literature review provides theoretical examples of the evolution of professional services (PS) staff. Changes in PS leadership roles are also explored alongside the emergence of 'Third Space' professionals whereby staff from the perceived 'binary' construct of HE (academics and PS staff) work together on shared initiatives outside formal structures. Semi-structured interviews with PS leaders working in AUs across the sector highlight a number of key themes. Findings suggest that documented tensions between academics and PS staff have lessened with the focus shifting to 'local' vs 'central' challenges. With identity emerging as an important consideration for Higher Education Professionals (HEPs), the paper calls for a sector wide review of structures and resource allocation models, the development of a new HEP apprenticeship scheme and a rebuilding of the PS throughout HE.
